Machine learning finds a surprising early galaxy – techtoday19

New results achieved by combining big data captured by the Subaru Telescope and the power of machine learning have discovered a galaxy with an extremely low oxygen abundance of 1.6% solar abundance, breaking the previous record of the lowest oxygen abundance. The measured oxygen abundance suggests that most of the stars in this galaxy formed very recently.
To understand galaxy evolution, astronomers need to study galaxies in various stages of formation and evolution. Most of the galaxies in the…
